The colors are beautiful, but it's a little grainy. Also, I'm not sure I like the head-on angle and how it's centered in a square. This adds abstraction (I never would have known what it was without the title), but I think it could be more dynamic from another view.
excellent invisible fan blades....... superior crop and image size!! A true abstract minimal image. Hot colours and light source (and temperture?) Centered and symmetrical. Easy to look at.
it would be helpful if you could see remnants of the individual wings. without it, I would don't sense any speed. I only know what it is by your title.
Unfortunately, I'll have to take your word that this is a ceiling fan. Apparently it was moving fast enough to be completely invisible to your camera, possibly excepting the left-side shadow. This looks like nothing but a slightly blurry photo of a light fixture, to my eyes...not something that gives me an illusion of speed. The yellow-orange cast is also highly distracting.
nice colors here - however the shot would have been more effective for me if I had been able to see some of the spinning blades. without the title I would assume this was just a light fixture.
